Ball Return Timing in Last 11 Seconds

[2010FRC0178]

Are teams assessed a penalty for not returning a ball if, according to the DOGMA, the ball would have to be returned in negative time?

For example, say we score in the last 6 seconds, and can't return the ball. According to <G05>, it's possible to assess the scoring at 10 seconds after the timer hits zero. Do we get a penalty?

No game PENALTIES are assessed after the game has concluded.
